Jesus memorized, He did not carry around books and scrolls, it was engrafted in His Head and Heart and Life.

bimodal (reading & hearing) Scripture helps memorize it, engrafting - well look that up in Scripture & SOP to see what that is and how to do it.
I think quite often about what will happen when the electricity is cut off at the end times.
If we don't have God's words in our gray matter now, what do we plan to do in that time?
Personally, I always take a few cards of Bible verses with me wherever I go, but I admit it is only a fraction of what I should have input by now.....
Bimodal reading/listening simultaneously seems to focus two learning centers input into memory faster than one mode alone.
Flash cards are handy as long as the ink stays color fast in the pocket.
